Missouri appears close to legalizing scalping (tickets, not heads).
The supply/demand arguments make a little bit of sense. (With legalized scalping there should be a greater supply, so prices will go down.) But that is dependent upon demand remaining steady. And I suspect there are people who refrain from buying scalped tickets — not because the price is higher, but they know they are ‘abetting a crime’ as the article puts it. Demand could go up as well. Maybe, as is so often the case on Ebay, supply will go up more.
It certainly falls in the category of ‘victimless crime’
